SPECIFICATION forming part of Letters Patent No. 643,417, dated February 13, 1900.

Application filed August 25,1899. Serial No. 728,457. (No model.)

To all whom, it'mcty concern:

Be it known that I, JOHANN HERMAN B. VON KiiNIGSLGW, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for Molding in Clay, Porcelain, &c.; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for molding in clay, porcelain, and other materials; and the invention consists in the construction, combination, and arrangement of parts of the machine,substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plain front elevation of one form or style of my new machine, slightly sectioned in one portion. Fig. 2 is a vertical sectional eleva tion of the machine on line 2 2, Fig. 1, showing especially the operative parts of the machine as disclosed on this line. Fig. 3, Sheet 2, is an elevation of the machine on a line corresponding to 3 3, Fig. 2, showing especially the cam-wheel and the ratchet mechanism operated thereby. Fig. 1 is a plan section on a line corresponding to 4 4, Figs. 1 and 2. Fig. 4: is a detail in section of a wick-finger for lubricating the finishing-plunger,as hereinafter described. Fig. 5 is a detail of a blank stick of clay or other material which has been prepared for molding into a tube in and by this machine. Fig. 6 is an elevation of the blank as it appears after undergoing the first step in the manufacture, and Fig. 7 is a longitudinal sectional elevation of a finished tube or product in position here to be ejected from the machine.

In the foregoing Views I represent a machine which is adapted to produce a variety of articles from clay, porcelain, or other moldable earthen material which has been suit-' ably prepared, whether in a powder, as for certain purposes, or in blanks, as for other purposes, and the views herein illustrated comprise means for operating with. both classes of material. The mechanism enabling this to be done necessarily is different in some particulars, as will hereinafter appear, but is the same in the essential principles of the invention.

Referring first to the form of the machine illustrated in the drawings, A represents the bed of the machine, and B an upright supporting-stem and plate fixed thereon.

G is the power-shaft, and D is the turret or mold-head in which the tubes are formed. This head serves as the main part for the molding of the tubes, and is provided with a series of cylindrical holes d,extending through from top to bottom in a circle and of the size of the tube or other article to be made, whether relatively of the size shown or larger or smaller. It rests on a base d of its own, which has a hole at one side registering with the holes or molds d as they are successively rotated around to that point in the intermittent forward rotary movement of the head.

To rotate the said head intermittently,'power is communicated from power-shaft O to the cam E, fixed on said shaft and which has a lug or projection 2 extending outward therefrom in position to engage a projection 3 on a rotatable wheel F on a shaft G. This wheel is free on shaft G and has an arm f, with a retracting-spring f and a pawl f thereon to engage a ratchet-wheel g, which is fixed on shaft G. Hence every time the Wheel F is turned by contact of the cam E therewith through lug 2 it will continue to turn until lug 2 disengages with lug 3 and ratchet g will be correspondingly rotated through pawl f and the shaft G therewith. Thisforward rotation is just enough to move the mold-head up one hole and no more. and 3 disengage the wheel F is thrown back to its initial and normal position by its retracting-spring f and is in position to be again engaged and rotated on the next revolution of cam E. This gives the desired intermittent movement to the mold or head D, and in the interim, when it is quiet, the tube or other article to be made is made and finished in the mold, so far as this part of the process is concerned.

On shaft G is a bevel-gear g which meshes with bevel-gear g on a short vertical shaft 9 This short shaft 9 projects up through baseplate 01, on which the head D rests and into said head, and it is temporarily fixed to the head by a nut d on its top, and the head is ro- Then as lugs 2 tated in this instance by reason of a small collar or disk on the shaft 9 set into the bottom of head D and having a pin g entering the head. By simply removing nut (Z a different head to produce a whollydifferent article may be substituted, and there is no limit practically to the many different things of widely-different design that may be made in this way. In this instance, however, the head is fashioned to make plain insulating-tubes with smallheads, and in Fig. 5 I show a blank stick of plastic clay or earth adapted to this use. It is set into the turret or molding head D by the operator one at a time as the head revolves to the right place, and in Fig. 6 we see the result of the first step in the conversion of the blank.

I may and preferably do use two plungers to bore and finish the tube, the plunger II doing the roughing work in forming the bore and the plunger 11 the finishing work and the two working successively on all the tubes in turn. Both pluugers are fixed to the same head 71., one in advance of the other the distance of one or more holes in mold-head D and both of a length to penetrate through said head and the tube therein. The plunger-rod H is fixed to a side lug on head h or supported in some other good way and at its bottom has a guide to hold it in alinement. The plunger H is held in the head It by an exteriorly-threaded and adjustable screw 7L3, and slidable on this plunger is a springpressed cap 7L to engage over the top of the tube as it is being formed, the spring 7L5 keeping it down.

The head 7b is rigid, with a sash or frame 7L2 sliding in suitable guides on the upright stem and plate B, and at the rear of the head It on said sash is a projection in which is supported a roller 71., adapted to run in a cam groove or channel in the face of cam E, which has been described as fixed 011 main shaft 0 to rotate therewith, the cam-groove c, in which roller 7L6 travels, being eccentric sufficiently to the shaft 0 to give the desired upand-down movement to the plungers, and of course are so arranged in respect thereto that the movements will be rightly timed.

Vhen the product or tube is finished, it is ready to be thrust out, and an ejector or ejecting-pin K is used for this purpose. This pin works from below upward, and it is carried up and down by a line of mechanism shown in Fig. I particularly. Here we see a parallel actuating-rod 7a, with an arm on its bottom in which ejector K is fixed. This rod slides up and down in a suitable support and has a tapered and shouldered head 4 at its top adapted to automatically engage between the pair of spring-pressed catches 5, pivoted together at their middle on a projection from the head h. When the head 7L descends, the head 4 of rod is gripped between the catches or dogs 5, and on its ascent the head It earries ejector K high enough to lift the finished tube bodily out of head D. A further movement brings the upper ends of catches 5 into the rounded socket 6 above and causes them to spread at their lower ends and release the rod 71" so that now it simply drops back with ejector K to its lowest place ready to be used again.

It is desirable to oil the finishing-plunger H, so that it shall leave a more finished and perfect bore in the tube and make smooth what might otherwise be a rough surface. To this end I employa wick-finger N, Fig 4, arranged in the machine to bear against the plunger practically its full length as the plunger descends, but so as to be rotated or carried to one side when the plunger is down. The means for doing this comprises a rotatable oil-supply-pipe section n,conneeted at its top by a suitable joint 12, with the oil can or reservoir a and having the wick-arm N fixed thereon at its lower end. On the pipe-section it is a sleeve a with a longitudinal channel deflected at about its middle out of its original line, and in this channel runs a pin a on head h. It follows when the head 7L descends that it runs into the lower part of said channel at the right time to swing the arm N laterally out of the way after the plunger has been oiled, and in the reverse movement the said arm is thrown back again to oiling position. It is curved at its extremity to engage about the plunger sufficiently.

About the bottom of turret or mold head D are a series of grooves or notches adapted to be engaged by a dog d, so that for the time there will be no movement of the said head, but it is released for rotation at the right time by means of a short bolt '7, which is pressed out against the upper end of the dog at by a projection 8 on the cam E, Fig. Otherwise the spring keeps the said dogin looking position.

In Fig. 7 I show a tube 20 beneath plate d and registering with one or both the plungerholes therein and constructed with a roughened interior more or less, and more or less air-opening near its top to prevent the clay from following the plunger back, and small holes 22 are made about the hole in the lower plate cl to ventilate from the inside out and avoid air-blisters in the tube at its corresponding end.

Vhat I claim as new, and desire to secure by Letters Patent, is

l. The mold-head having openings through from top to bottom and means to rotate said head, in combination with a stationary baseplate having a discharge-opening for the surplus product received from the mold-openin gs, a forming-plunger above said discharge-opening, a receptacle below said discharge-open ing to receive the cast-off stock and means within said receptacle to prevent the stock from following the plunger back,substantially as described.
